Project scenario:

Windows10 + python3.6 + pyvista0.31.3

Problem Description:

Problem Description: after upgrading the windows system, a strange error suddenly appeared in the well run code about pyvista visualization ply file some time ago:

ERROR:root:GLEW could not be initialized: Missing GL version

Cause analysis:

After upgrading windows, some things have been added to the environment variable path, resulting in the environment variable being too long, exceeding the maximum length of 1023 characters, and the following environment variables have been truncated.

Solution:

Find a way to shorten the path of the environment variable, delete some paths that are not used very much, or use RapidEE environment variable editing tool to optimize
